The Coach Rage Scale, From Harbaugh To Carroll

Football coaches, in the NFL or Europe, may never have been the target audience of Rage Against The Machine. But the above lyric hollered by singer Zach de la Rocha during the leftist band's heyday could probably have newly minted University of Michigan head football coach Jim Harbaugh singing along with even the most anti-sports student ever to rock a Che Guevara shirt in Ann Arbor. Whether coaching in the NFL or at the college level, Harbaugh's anger has seemed to fuel his teams nearly as much as his X's-and-O's acumen. While Harbaugh may be among the foremost purveyors of rage in the wide world of sports, he is hardly alone in displaying a fiery persona on the sideline.

From Harbaugh's unadulterated referee nightmare fuel to laissez-faire laughter of his former NFC West rival, here is The Coach Rage Scale, ranking sideline histrionics on a scale of 1-10.
